Hello. Typically in a circumstance such as this, a mechanic would pressurize the cooling system when cold, so as to allow up-close inspection, and identify the leak. A non functioning cooling fan can cause overheating which indirectly could cause coolant...

The symptoms you describe on your GMC Sierra lead me to believe that the issue lies with the battery, starter or the wiring that joins these two components together. It is also possible to have issues with all three. You...

Hello - the gurgling noise is most likely a cooling system issue - perhaps overheating that has not yet caused a failure. Check coolant level (engine cold), and the transmission fluid level as well. Look for clear, pinkish (not dark)...

Shift points are controlled by vehicle sensors such as the vehicle speed sensor and throttle position sensor. In addition there are shift solenoids in the transmission valve body and, in the scenario you are presenting, torque converter lock up controls....

Billing question sent to CS for the cost to replace the battery, replace the vehicle speed sensor (VSS), and clear the engine light.

It appears like your Hyundai is having issues with one or more of the components that aid in the process of shifting your vehicle. Due to the information provided being limited, it is difficult to determine whether the concern falls...

Your car may be equipped with tilting Head Restraints. This provides additional comfort, but it’s not available on all models. If yours is so equipped, here’s how you work them: Make sure the seatback is in the right position...

Hi there. A couple of small spots is sure sign that something is leaking. What color are the spots? If they are dark they could be engine oil, if red they could be transmission fluid. A leak is something that...

You can use an infrared thermometer to measure rotor temperature from side to side and that might give an indication that a caliper is perhaps not retracting. Calipers should be discarded based on mileage and/or years in service. A prudent...

The blue smoke is due to oil leaking into the combustion chambers. The cause can vary from fairly easy to fix worn out valve stem oil seals to more costly faults such as leaking piston rings or head gasket failures....

A few things to check before you condemn the engine. Sometimes a coolant leak can get into the cylinders of the engine when it is sitting. This will hydro-lock the engine. Water above the piston does not compress and will...

Hello, thank you for writing in. The first thing we need to discuss is the testing of starters. Starters are only bench tested typically, which means they hook up a power supply and watch for it to function. What they...

Sort of taking a flier on this one, but I suspect the "fail" designation would be assigned if the exhaust manifold were leaking. If so, exhaust fumes could then enter the vehicle through the fresh air vents and cause carbon...

The rear cup holders are located in the in the rear seat armrest. Just pull down the armrest.

Hi there. To remove the fuel rail, simply remove the bolts that secure the rail onto the intake manifold and all of the brackets off the rail. Take a pry bar and gently pry up on the fuel rail to...

The auto-up and auto-down features allow you to entirely roll up or down a power window with one press of a button. Sometimes the auto-up and auto-down functions stop working, and need to be reactivated. To do this, pull the...

Engine stalls are often caused by a malfunctioning sensor if not lack of fueling or ignition system maintenance. A trained technician will take them all into consideration. Worn spark plugs may cause a stall on their last leg and prove...

It sounds like you are referring to delayed shifting. That can be caused by an inadequate amount of transmission fluid, solenoid faults, faults in internal transmission hydraulic pressure control, engine control faults (e.g., throttle position sensor), and many other types...

I think you should get a second opinion on this. The wiring harness should be trouble free unless something has happened to damage it. Accidents, fires, water damage, salt corrosion, or electrical overloads can damage a wiring harness, but you...

Hi there. Has the system been charged recently? If so, there could be too much refrigerant in the system causing the pressure valve to vent the excess pressure; the high pressure sensor is there to prevent catastrophic system failure and...

If your vehicle is shaking very badly, it is possible that you have an engine or transmission mount that is worn. These mounts are made of rubber and when they wear out, they cause the engine to shake. This vibration...
